Sheet #687u – Displaying results in flow unit
Version 1.04a User guide ATEQ 6th series Page 3/3
2) Start a second cycle with the same part but
with the master leak connected to the device
.
The result displayed on the instrument should
be:
Test result w/o leak + Value of the leak.
If the result displayed on the instrument is
different than test result w/o leak + Value of
the leak: we need to adjust the volume value
inside the program parameters.

Back to the parameter page, and select the
“VOLUME” parameter to correct it.
The relationship of the volume and the result
is linear. If the displayed result is 10% higher
than the
calibrated leak value + Test result w/o leak,
reduce the volume by 10%.
Wait one minute between test cycles to
ensure accurate results. Repeat as necessary.

FUNCTIONS
The formula that the instrument uses to convert Pa/s to cc/min is:
Leak in Pa/s =
Leak in cc/min
olume x 0.0006
If the option "Pa DISPLAY" is validated by
"Yes" in the parameters, the leak result with
the Pa unit is simultaneously displayed with
the flow unit result.
